Automapper如何动态更改映射

Question

我正在连接一些WebService并接收Dictionary 包含键：“firstName”，“lastName”，“otherfirstName”，“otherLastName”。

我有对象人

public class Person
{
  public string FirstName{get;set;}
  public string LastName{get;set;}
}

根据某些上下文，我应该通过映射“firstName”和“lastName”中的值来创建我的对象Person，在另一种情况下，通过映射来自“otherfirstName”和“otherlastName”

如果我只能创建一个映射函数，我如何映射到其他人并动态地在它们之间进行更改？

Mapper.CreateMap<Response, Person>()                
.ForMember(dest => dest.FirstName, opt => opt.MapFrom(src => src.Dict["firstName"] : "") ))
.ForMember(dest => dest.LastName, opt => opt.MapFrom(src => src.Dict["lastName"] : "") ));

我在Profiles中看到了一些用法，但我不确定如何在我的情况下使用它。

被修改

public class FirstMapper : Profile
{
    protected override void Configure()
    {
        base.Configure();
        Mapper.CreateMap<Src, Person>()
        .ForMember(dest => dest.FirstName, opt => opt.MapFrom(src => src.Dct["firstName"]))
        .ForMember(dest => dest.LastName, opt => opt.MapFrom(src => src.Dct["lastName"]));

    }
}


public class SecondMapper : Profile
{
    protected override void Configure()
    {
        base.Configure();
        Mapper.CreateMap<Src, Person>()
        .ForMember(dest => dest.FirstName, opt => opt.MapFrom(src => src.Dct["otherfirstName"]))
        .ForMember(dest => dest.LastName, opt => opt.MapFrom(src => src.Dct["otherlastName"]));

    }
}


 public class Src
     {
        public Dictionary<string, string> Dct { get; set; }
    }

我的测试课

public class Test
{
    public Test()
    {
        Src src = new Src();
        src.Dct = new Dictionary<string, string>();
        src.Dct["firstName"] = "La";
        src.Dct["lastName"] = "Nu";
        src.Dct["otherfirstName"] = "Fe";
        src.Dct["otherlastName"] = "oooo";

        Person person = new Person();

        ConfigurationStore store   = new ConfigurationStore(new TypeMapFactory(), MapperRegistry.Mappers);
        store.AssertConfigurationIsValid();

        MappingEngine engine = new MappingEngine(store) ;

        //add mappings via Profiles or CreateMap

        store.AddProfile(new FirstMapper());

        person = engine.Map<Person>(src);

}
